The Munsell color system, showing: a circle of hues at value 5 chroma 6; the neutral values from 0 to 10; and the chromas of purple-blue (5PB) at value 5. In colorimetry, the Munsell color system is a color space that specifies colors based on three properties of color: hue (basic color), value ( lightness ), and chroma (color intensity).
The (un-normalized) color matching functions are the amounts of primaries needed to match the monochromatic test primary. These functions are shown in the plot on the right (CIE 1931). and are zero at 435.8 nm, and are zero at 546.1 nm and and are zero at 700 nm, since in these cases the test color is one of the primaries.
Albert Henry Munsell (January 6, 1858 – June 28, 1918) was an American painter, teacher of art, and the inventor of the Munsell color system . He was born in Boston, Massachusetts, [1] attended and served on the faculty of Massachusetts Normal Art School, and died in nearby Brookline . As a painter, he was noted for seascapes and portraits.
In colorimetry and color appearance models, lightness is a prediction of how an illuminated color will appear to a standard observer. While luminance is a linear measurement of light, lightness is a linear prediction of the human perception of that light. This distinction is meaningful because human vision's lightness perception is non-linear ...
The Munsell color system. The image shows: * The neutral values in steps of 1 from 0 to 10 * A circle of 10 hues at value 5 and chroma 6 * The chromas of purple-blue in steps of 2 from 0 to 12, at value 5 The colors should be
ISCC–NBS system. The ISCC–NBS System of Color Designation is a system for naming colors based on a set of 13 basic color terms and a small set of adjective modifiers. It was first established in the 1930s by a joint effort of the Inter-Society Color Council (ISCC), made up of delegates from various American trade organizations, and the ...
Munsell's system became extremely popular, the de facto reference for American color standards—used not only for specifying the color of paints and crayons, but also, e.g., electrical wire, beer, and soil color—because it was organized based on perceptual measurements, specified colors via an easily learned and systematic triple of numbers ...
